Smith was accused of shooting and killing four people early Sunday morning at a car wash in Melcroft, located about 55 miles southeast of Pittsburgh. Investigators believe he then turned the gun on himself.

The victims -- identified as William Porterfield, 27; Chelsie Cline, 25; Courtney Snyder, 23; and Seth Cline, 21 -- were pronounced dead at the scene. There was a fifth person with the victims that night who managed to escape with minor injuries.
